Results
The lymphocyte subsets of the antrum and lesser curvature of the body were similar. In contrast, compared to those in the greater curvature of the gastric body, CD4+/CD3+ lymphocyte subsets were elevated in the lesser curvature of the body, whereas CD8+/CD3+, CD7+/CD3+, CCR4+/CD3+, CD45RA+/CD3+CD4+, and CD45RA+/CD3+CD4- were lower. Linear regression analysis showed a negative correlation between the time after H. pylori eradication and CD4+/CD3+.

Baseline Characteristics
To investigate site-specific differences in stomach-resident T lymphocytes after H. pylori eradication, we performed flow cytometry analysis on samples taken from the gastric antrum, greater curvature of the gastric body, and lesser curvature of the gastric body of 20 patients.
